Behind the Scenes of The Hunt for Dzhokhar Tsarnaev

Law enforcement officials converge on the boat in Watertown where Tsarnaev is hiding.

It was likely the most terrifying manhunt in Boston history. With the city under lockdown and armored vehicles rolling through Watertown, the alleged Boston Marathon bomber Dzhokhar Tsarnaev had seemingly vanished. While the rest of Greater Boston experienced the unfolding dragnet on April 19 as a series of indirect glimpses, Sergeant Sean Murphy, in his assignment as a tactical photographer with the Massachusetts State Police, was behind police lines, documenting the day’s events.
